Such as VOIP actually, or other digital technologies that are now quite

I doubt that they are using VoIP, though, which is notoriously
unreliable.

You should a bit of reading before you make such comments. I happen to be in
the public safety communications field, and we are right now phasing out our old
trunked FM system for a VOIP system. We have already scrapped our old phone
systems in favor of VOIP and that is working just fine. If VOIP were
"notoriously unreliable" we would hardly use it for public safety
communications.
